Subject : Relationship model for English-German dictionary
Question: I am looking for an optimal solution for data model for a dictionary. 

At first dictionary will have only 2 languages: English and German, 
but there should be possibility to add more languages (Finnish, Swedish, Amharic). 

My problem is that there is easily coming many to many relationships and the structure of database will be blurred. 

For instance English words for car: 
1. car
2. automobile 

and in German: 
1. der auto, 
2. der mobile 

What kind of data model structure would be most optimal for this kind of basic dictionary database ?

B. Things of Interest :-
B.1 Languages
B.2 Synonyms
B.3 Words

C. How are they related ?
C.1 A Word can translate into one or many Words in another Language.
